Answer and Explanation:
One of my experiences that can be cited is the long trips I made, between states, using a travel bus. This source would be important to describe scenarios, in a literary work, since a bus trip allows us to see different real scenarios, since the trip is long and passes through different territories.
Another source would be my family relationship. This would be a very rich source, as family relationships have several good and bad moments and several memories can be explored.
My high school experiences could also be used, the friendships I built, the subjects that I found easy and difficult, the difficulties of socializing and the fun moments.
It is also possible to explore my experiences in the sport (tennis, in this case), my training, difficulties and plans. This can be used as a source to design a character's plans and an activity to which he engages.
Finally, it is possible to explore my experiences when camping or doing some activity in nature, the dangers and the satisfaction of this type of activity.
Derek enjoys playing baseball with his friends, going on camping trips with his dad, and traveling to different cities throughout the year.When I go to the park, I like bringing a blanket and to pack a picnic basket full of sandwiches and fruit.
I like playing hockey more than I like to play soccer. Jonathan enjoys watching comedy at the movie theater more than he likes watching horror films at the movie theater.
This is the correct form, though you need to be specific and describe who "them" is.
